Presentation of the communication campaignA number of

thematic ecogestures are being promoted for all amU students and staff. The ecogestures aim to encourage energy sobriety, but they also address other themes, notably sustainable mobility and the lifespan of equipment, major challenges in reducing the University's greenhouse gas emissions.

Each eco-gesture is associated with a key figure to illustrate its environmental impact, as well as with an action taken by the University to try to reduce this impact.

As the sum of all individual initiatives has a significant impact on a large scale, the adoption of these ecogestures by as many people as possible will contribute to the university's efforts to reduce its environmental footprint. Sustainable development is everyone's business.

Together, let's adopt the Ecogestes!

Geste 1 : privilégier une utilisation raisonnée de la climatisation

Air conditioning is not always necessary. In summer, simple gestures can often help keep the house cool. Open windows in the morning and close them when the outside temperature rises, or use fans, which consume less energy. For staff with air-conditioning, and when working conditions allow, it is advisable to use air-conditioning sparingly. For example, switching

from

a set temperature of 22°C to 27°C can halve the energy consumption of air-conditioning units.

air-conditioning is:

• ADEME data: Air-conditioning at 27°C instead of 22°C = Energy consumption halved by 2
• amU action: Â鶹tv installs photovoltaic panels on its campuses to reduce the impact of its energy consumption
• Ecogest: Air-conditioning is not automatic! Stay on course for 26°CEco-task

2: Opt for a gentler mode of transport

The greenhouse gas emissions balance (BEGES) for amU 2022 shows that 68% of the University's emissions in 2021 are linked to staff and student travel. Mobility is therefore a major lever for reducing the establishment's footprint. To this end, amU encourages the use of soft modes of transport: walking, cycling, scootering, public transport, etc. Staff using bicycles or scooters are also eligible for the sustainable mobility package, a financial support scheme for staff commuting to and from work. A car-pooling incentive scheme common to AMP Métropole is also in place, operated by KAROS.

Mobility means:

• amU BEGES data: 68% of amU's CO2 emissions come from
• travelamU action: Â鶹tv supports cycling and
• carpoolingEco-gesture: Think sustainable mobility! Move with panacheGeste

3 : sort, delete and archive your e-mails

The impact of sending an e-mail depends on :

• Server storage timeThe
• weight of attachments.
• It's best to use compressed files, images and low-definition PDFs where possible, and to use links to hosted sources (such as AMUbox)
• .
• It's a good idea to target recipients and limit the number of messages you

sendThere are a number of options for using e-mail wisely (depending on your organization):

• Delete unnecessary messages (advertising, notifications, etc.).)
• Immediately process messages requiring a short reply
• Archive messages requiring no action on your part, but linked to a project follow-up, in a folderCreate
• folders to classify e-mails you wish to keep by theme/project, or keep only a few folders, such as "Urgent", "In progress", "Follow-up" and "Archives "

E-mails are :

• amU data: Within the University, 1 e-mail sent is duplicated on 4
• serversamU action: Â鶹tv blocks 3 million unwanted e-mails a
• dayEco-gesture: Sort, delete and archive your e-mails! Skim your

mailboxEcoGeste 4 : Use natural light

As light accounts for around 7% of the university's electricity consumption, we recommend that you use natural light from windows whenever possible and when weather conditions allow. An (all too often neglected) automatic feature that can help you make substantial savings? Turn off the light when you leave a room! amU is also committed to gradually deploying 100% low-energy interior lighting.

Light is:

• ADEME data: 20% of a tertiary building's electricity consumption comes from
• lightingAmU action: Aix Marseille Université is committed to deploying 100% low-energy interior
• lightingEco-gesture: Give preference to natural light! Neon lights aren't as niceGeste

5 : in winter, opt for a heating setting of 19°

The drop in temperatures in winter naturally leads the establishment to start heating its facilities. For those who can, the reflex is sometimes to set the heating temperature much higher than the national recommendations (19°C), leading to high energy consumption. However, this choice of higher heating temperature represents a considerable additional cost and energy consumption! Did you know that choosing to lower the thermostat by 1°C can save you around 7%? So it's time to bundle up and, for those who can, choose a room temperature of 19°C.

Heating is:

• ADEME data: 1°C more = +7%
• consumptionAMU action: Aix-Â鶹tv is carrying out energy renovation work on its buildings.
• Ecogesture: Sobriety means choosing 19°C!

Gesture 6: Extend the life of equipment

Extending the life of equipment is one of the most effective ways of reducing our carbon footprint. Indeed, for a 2kg computer, for example, ADEME points out that its manufacture requires around 800kg of raw materials - not counting the energy used. Furthermore, it is estimated that 75% of a computer's total impact in terms of greenhouse gases is linked to its construction. 

Making equipment last is therefore the most effective eco-gesture for reducing its impact. Extending the lifespan of a computer from three to six years reduces its environmental impact by 50%.

Equipment is:

• ADEME data: 75% of the total greenhouse gas impact of a computer is linked to its construction
• AMU action: Â鶹tv extends the warranty on its computers to 7 years
• The ecogest: Make your equipment last! Win the race in the long runEcoGeste

7 : Connect by videoconferencing

According to the latest AMU greenhouse gas emissions assessment in 2022, mobility-related emissions accounted for 68% of the total. Against this backdrop, it is crucial to implement measures aimed at reducing the distances travelled. Among these, the use of videoconferencing for meetings is an effective way of reducing the company's environmental impact. While these methods are not suitable for all meetings, amU encourages the use of videoconferencing for short meetings, if this reduces the need to travel.

videoconferencing can also be a relevant way of reducing the environmental impact of conferences or symposia, particularly if participation in person requires a long-haul flight. A study published in Nature communications in 2021 estimates that switching to remote participation for a conference can reduce the carbon footprint by 94%.

Commuting is:

• BEGES amU data: 68% of amU's CO2 emissions come from travel
• AMU action: amU encourages remote meetings to reduce its carbon
• footprintEcoGeste: Connect by videoconference! Save your journeysODD
